Marginal and
absorption costing
this chapter covers...
This chapter focuses on the costing methods of marginal and absorption costing and
compares the profit made by a business under each method. The chapter concludes
with the layout of a manufacturing account and statement of profit or loss (income
statement) and where the different types of inventory – raw materials, work-in-progress,
finished goods – are shown in the financial statements.
This chapter explains:
n the different treatment of product costs and period costs in marginal costing and
absorption costing
n how marginal costing works, including the calculation of contribution, and its role in
short-term decision-making
n how absorption costing works, including the valuation of closing inventory

marginal and absorption costing systems
These two costing systems are often used in cost accounting, but for different
purposes:
n marginal costing – helps with short-term decision-making
n absorption costing – is used to calculate inventory valuations and profit
calculations in financial statements
The use of each system is dependent on the information needs of the business
or organisation:
– ‘can we afford to sell 1,000 units of our product each month to
Megastores Limited at a discount of 20 per cent?’ (use marginal
costing)
– ‘what profit have we made this year?’ (use absorption costing)
These costing systems use the same costs, but they are treated differently
according to their behaviour. We will now look at each of these costing
systems in turn and then make a comparison between them.
marginal costing
Marginal cost is the cost of producing one extra unit of output
To help with short-term decision-making, costs are classified by their
behaviour as either variable costs or fixed costs (with semi-variable costs
being split between their fixed and variable parts). Such a classification of
costs is used in marginal costing to work out how much it costs to produce
each extra unit of output.
Marginal cost is often – but not always – the total of the variable costs of
producing a unit of output. For most purposes, marginal costing is not
concerned with fixed period costs (such as the rent of a factory); instead it is
concerned with variable product costs – direct materials, direct labour, direct
expenses, and variable production overheads – which increase as output
increases. For most decision-making, the marginal cost of a unit of output is,
therefore, the variable cost of producing one more unit.
Knowing the marginal cost of a unit of output enables the managers of a
business to focus on the contribution provided by each unit. The contribution
is the sales revenue after marginal/variable product costs have been paid. The
contribution formula is:
selling price less variable cost = contribution
202
analysing costs and revenues tutorial
Contribution can be calculated on a per unit basis (as here), or for a batch of
output (eg 1,000 units), or for a whole business.
It follows that the difference between the sales revenue and the variable costs
of the units sold in a period is the total contribution that the sales of all the
units in the period make towards the fixed period costs of the business. Once
these are covered, the remainder of the contribution is profit.
Thus a business can work out its profit, using a marginal costing statement,
for any given period from the total contribution and fixed costs figures:
total contribution less total fixed costs = profit
A marginal costing statement can be prepared in the following format:

Note from the marginal costing statement how the contribution goes firstly
towards the fixed costs and, when they have been covered, secondly
contributes to profit.
The relationship between marginal costing, contribution and profit is shown
in the Case Study which follows.

advantages of a marginal costing statement
A marginal costing statement is of benefit to the managers of a business
because:
n contribution, ie selling price less variable cost, is clearly identified
n with the marginal cost of output identified, the managers can focus on the
contribution provided by the output
n the effect on costs of changes in sales revenue can be calculated
n it helps with short-term decision-making in the forms of
– break-even analysis
– margin of safety
– target profit
– contribution sales ratio
– limiting factors
– ‘special order’ pricing
We will look at the role of marginal costing in short-term decision-making in
Chapter 9.
absorption costing
Absorption costing absorbs the costs of the business amongst the cost
units.
Absorption costing answers the question, ‘What does it cost to make one unit
of output?’
The absorption cost of a unit of output is made up of the following costs:

Conclusion
Profit for the week of £6,000 is the same as with the marginal costing method, so we
could say ‘Does it matter whether we use marginal or absorption costing?’ The answer
to this is that it does:
– marginal costing, with its focus on variable costs and contribution, is useful for shortterm decision-making
– absorption costing is a simple method of calculating the cost of output and is used
in financial statements for inventory valuation
206
analysing costs and revenues tutorial
As the Case Study shows, each cost unit bears an equal proportion of the
costs of the production overheads of the business. Because of its simplicity,
absorption costing is a widely used system which tells us how much it costs
to make one unit of output. It works well where the cost units are identical,
eg 100 identical bikes, but is less appropriate where some of the cost units
differ in quality, eg 100 bikes, of which 75 are standard models and 25 are
handbuilt to the customers’ specifications. It also ignores the effect of
changes in the level of output on the cost structure. For example, if the bike
manufacturer reduces output to 50 bikes a week:
n will direct materials remain at £40 per bike? (buying materials in smaller
quantities might mean higher prices)
n will direct labour still be £50 per bike? (with lower production, the
workforce may not be able to specialise in certain jobs, and may be less
efficient)
n will the production overheads remain at £5,000? (perhaps smaller
premises can be used and the factory rent reduced)
m a r g i n a l a n d a b s o r p t i o n c o s t i n g c o m pa r e d
Marginal costing tells the managers of a business or organisation the cost of
producing one extra unit of output. Nevertheless, we must always remember
that one of the objectives of the costing system is to ensure that all the costs
of a business or organisation are recovered by being charged to production.
This is achieved by means of overhead absorption (see Chapter 5). We will
now make a comparison between marginal and absorption costing:
n marginal costing
Marginal costing recognises that fixed period costs vary with time rather
than activity, and identifies the variable production cost of one extra unit.
For example, the rent of a factory relates to a certain time period, eg one
month, and remains unchanged whether 100 units of output are made or
whether 500 units are made (always assuming that the capacity of the
factory is at least 500 units); by contrast, the production of one extra unit
will incur an increase in variable costs, ie direct materials, direct labour,
direct expenses (if any), and variable overheads – this increase is the
marginal cost.
n absorption costing
This technique absorbs all production costs into each unit of output
through the use of an overhead absorption rate (see Chapter 5). Therefore
the more units that are produced, the cheaper will be the cost per unit –
because the overheads are spread over a greater number of units.
marginal and absorption costing
207
The diagram below demonstrates how the terms in marginal costing relate to
the same production costs as those categorised under absorption costing
terms. As noted above, when using marginal costing it is the behaviour of the
cost – fixed or variable – that is important, not the origin of the cost.

The table on the next page gives a comparison between marginal costing and
absorption costing, including a note on the usefulness and the limitations of
each.
marginal and absorption costing: profit comparisons
Because of the different ways in which marginal costing and absorption
costing treat fixed period costs, the two techniques produce different levels
of profit when there is a closing inventory figure. This is because, under
marginal costing, the closing inventory is valued at variable production cost;
by contrast, absorption cost includes a share of fixed production costs in the
closing inventory valuation. This is illustrated in the Case Study which
follows, looking at the effect of using marginal costing and absorption
costing on the statement of profit or loss of a manufacturing business.
Note that the marginal cost approach is used to help with short-term
decision-making (see Chapter 9). However, for financial statements,
absorption costing must be used for inventory valuation purposes in order to
comply with IAS 2 (see page 44). Under IAS 2, Inventories, the closing
inventory valuation is based on the costs of direct materials, direct labour,
direct expenses (if any), and production overheads. Note that non-production
overheads are not included, as they are charged in full to the statement of
profit or loss in the year to which they relate.

Tutorial notes:
• Closing inventory is always calculated on the basis of this year’s costs:
marginal costing, variable costs only, ie £30 + £40 = £70 per chair
absorption costing, variable and fixed costs, ie £450,000 ÷ 5,000 chairs = £90 per
chair
• The difference in the profit figures is caused only by the closing inventory figures:
£35,000 under marginal costing and £45,000 under absorption costing – the same
costs have been used, but fixed production overheads have been treated differently.
• Only fixed production overheads are dealt with differently using the techniques of
marginal and absorption costing – both methods charge non-production overheads
in full to the statement of profit or loss in the year to which they relate.
With marginal costing, the full amount of the fixed production overheads has been
charged in this year’s statement of profit or loss; by contrast, with absorption costing,
part of the fixed production overheads (here, £10,000) has been carried forward in the
inventory valuation.
With regard to the directors’ statement that they will use ‘the one that shows the higher
profit’, the following points should be borne in mind:
• A higher profit does not mean more money in the bank.
• The two methods simply treat fixed production overheads differently and, in a year
when there is no closing inventory, total profits to date are exactly the same – but
they occur differently over the years. Over time, profits are identical under both
methods.
• For financial statements, Chairs Limited must use the absorption cost inventory
valuation of £45,000 in order to comply with IAS 2, Inventories.
t H e u s e o F a m a n u Fa c t u r i n g a c c o u n t
Now that we have seen how a manufacturing business uses absorption
costing to value its closing inventory, we can turn our attention to the yearend financial statements and, in particular, the use of a manufacturing
account.
For preparing financial statements a business needs to have an accounting
system that records the costs and revenues for its output, and then shows the
profit or loss that has been made for the accounting period. For a business
such as a retailer that buys and sells goods, without carrying out any
production processes, the accounting system is relatively simple – the figure
for revenue is deducted from the amount of purchases (after allowing for
changes in the value of opening and closing inventories) and the amount of
overheads; a profit is made when revenue exceeds the total costs. For a
marginal and absorption costing
211
manufacturer, though, the costs are more complex as they comprise the direct
and indirect costs of materials, labour and expenses; also, a manufacturer
will invariably have opening and closing inventory in three different forms –
direct materials, work-in-progress and finished goods.
In its year-end financial statements a manufacturer prepares:
n a manufacturing account, which shows production (factory) cost
n a statement of profit or loss, which shows profit for the period
The financial statements, which are part of the double-entry system, use the
following outline:

n Adjustments have to be made to allow for changes in the value of
inventory at the start of the accounting period (opening inventory) and at
the end of the accounting period (closing inventory) for:
– direct materials, in the manufacturing account
– work-in-progress (or partly manufactured goods), in the
manufacturing account
– finished goods, in the statement of profit or loss
212
analysing costs and revenues tutorial
n The statement of profit or loss shows two levels of profit:
– gross profit, the difference between selling price and production cost
(after allowing for changes in the value of opening and closing
inventory)
– profit for the year, the profit after all costs have been deducted and
which belongs to the owner(s) of the business
n Certain expenses might be apportioned on an appropriate basis between
the manufacturing account and the statement of profit or loss – for
example, rent and rates might be apportioned 75 per cent to the factory
(production overheads) and 25 per cent to the office (non-production
overheads)
An example of a manufacturing account and statement of profit or loss is
shown on the next page.
Chapter
Summary
n Marginal costing classifies costs by their behaviour – variable product costs
or fixed period costs. Such a classification is used to cost units of output on
the basis of their variable (or marginal) costs.
n Marginal costing helps with short-term decision-making.
n Absorption costing absorbs the costs of the business amongst the cost units
by means of overhead absorption rates. It is used to cost units of output to
calculate inventory valuations for financial statements and to calculate profit.
n A manufacturing account is a financial statement which shows prime cost and
production (factory) cost.
n A statement of profit or loss shows non-production overheads and profit for
the year of the business.
